FUNCTIONS

convert_unit

Usage:

Convert a physical quantity from one unit to another.

Examples:

• Show all possible conversions for speed:

  
              
  
                
                
  convert_unit(quantity => "m/s");
              
            

  Result:

  
              
  
                
                
  [
    { amount => 3.33564095198152e-09, unit => "c" },
    { amount => 3.28083989501312, unit => "fps" },
    { amount => 3600000000000, unit => "knot" },
    { amount => 3600000000000, unit => "knots" },
    { amount => 3.6, unit => "kph" },
    { amount => 0.001, unit => "kps" },
    { amount => 2.2369362920544, unit => "mph" },
    { amount => 1, unit => "mps" },
    { amount => 3.33564095198152e-09, unit => "speed-of-light" },
  ]
              
            

• Convert from meters/sec to kilometers/hour:

  
              
  
                
                
  convert_unit(quantity => "40 m/s", to_unit => "kph"); # -> 144
              
            

If target unit is not specified, will show all known conversions.

This function is not exported.

Arguments ('*' denotes required arguments):

• quantity* => str

• to_unit => physical::unit

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
